COMBINED GAS SUPPLY AND LIGHTING DEVICE.

To all 'LU/wm t may concern.'

Be it known that I, ELBY R. MILLS, a citizen of the United States, residing at Sabina, in the county of Clinton and State of Ohio, have invented certain new and useful Improvements in Combined Gas Supply and Lighting Devices, of which the following is a specication.

My invention relates to the improvement of combined gas supply and lighting devices, and has particular relation to devices oit' that class which are to be used in connection with automobile lighting.

The objects or' my invention are to provide a simple, inexpensive and reliable mechanism by means of which a desirable quantity ot gas under a predetermined pressure may be supplied to automobile or other lamps, the gas thus supplied being ignited through the operation of the gas controlling valve; to so construct my device as to provide improved means for adjusting the valve handle with relation to the valve stem and to otherwise produce an effective device of the class mentioned in which by a single operation of a controlling lever, a lamp or lamps may be supplied with a desirable quantity and pressure of gas and simultaneously ignited. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section of my device, Fig. 2 is a view in elevation thereof at right angles with that shown in Fig. 1, and, Fig. 3 is a plan view.

Similar' numerals refer to similar parts throughout the several views.

In carrying out my invention, I employ an upright valve casing body comprising lower and upper sections 1 and 2, the lower section having its upper portion vertically recessed to form a chamber 1a and the upper port-ion of said chamber being normally closed by having threaded in connection therewith the. lower externally threaded portion of the upper section 2. The connection ot' the members 2 and 1, is rendered further gas tight by the employment of a suitable gasket 3, .which is interposed between a peripheral ange of the member 2 and the upper end of the member or section 1.

Specification of Letters Patent.

Application filed February 16, 1911.

Serial No. 698,912.

The lower end of the chamber 1a is tapering or conical as shown and leading from the apex of the inverted cone-shaped recess thus itorrned, is a central downwardly eX- tending gas port or passage at, the lower end oit the latter leading into the apex of the cone-shaped upper end of a similar gas chamber 5, which is provided in the lower portion of the section l. This gas chamber 3 on one side, communicates with a laterally extending passage 6, which through the medium. of a tube 7, is extended outward and suitably connected with a storage gas tank not herein shown. The tubular member 7 may be formed separately from the casing section l and screwed in connection therewith as shown, or it is obvious that the same may be cast with said casing section. y'the lower end of the casing section 1 is formed with a downwardly extending tubular and externally threaded neck 8, in which is rotatably mounted the stem of a vertical needle-point valve 9, the latter having a threaded connection with an opening in the lower part of the casing section 1 and having its conical valve termination adapted to seat in the conical upper end of the chamber 5 and to control the iow of gas through the passage The casing neck extension 8 and a portion or the stem of the valve u, is incas-ed by a suitable packing uut l()-r in which is provided about said valve stem, suitable packing 1l.

Leading out or the chamber l is a pipe section or tubular member 12 which may be connected in any suitable manner with the burners of one or more lamps. Extending newnwardly through the reduced upward extension neck Qa ot the casing section ,J

2, is a rotary valve stem 13, the threaded portion oit' said stem engaging internal threads in .said member 2, while the lower portion of the stein is provided with the usual needle point valve termination 13a, which is adapted to close or regulate the opening of the upper end of the port or passage -l-. fit the point of entrance of the valve stein 13 into the casing neck 2, I provide a stuliing box or packing nut 13b adapted to prevent leakage of the gas about said stem. The upper end portion of the stem 18 passes through a vertical opening"` desirable quantity of additional gas supwhich is 'termed through an operating lever l or handle 14.Y toward one end ot the latter.

As indicated in the drawing, this end portion of the lever le' is sollt verticall the s )ht thus termed and which is indicated at 111 leading 'from the opening through which the stem 13 passes out through the end ot the lever. 0n the outer side ot the valve stem 18, the portions oit' the lever which are separated by the split 1a are connected by a transverse screw 1.5, the tightening or loosening of which regulates the trictional engagement of `the lever or handle with said valve stem.

Mounted on one side of the upper portion ot' the valve casing, is an upright insulating block or plate 16, which may be ot any suitable non-conducting material. Connected with the upper portion of this insulating plate is a suitable wire binding post 17, said insulator also having' connected therewith an upwardly extending vertical contact plate or strip .18.

It will be readily understood that the volume and pressure ot gas which may pass from the gas supply tank through the tubular member 7 and chamber 5, and thence through the port or passage Ll, may be regulated by the position of the needle point valve 9, which may be so set with relation to the lower end of the port 4t, as to admit ot the passage ot but a predetermined quantity of gas. In the drawing, l have shown the controlling needle valve in its lowered or closed position, but it is obvious that when the valve 9 is properly opened and 'the valve 18 raised from its seat, the desired quantity of gas will flow through the chamber 5, the passage or port l, chambe1 1a and tubular member 12 to the burners. lt will be also observed that when the valve 13 is closed, the lever or handle 1ais so turned as to cause the contact extension A@ of its split end to extend in a direction parallel with the tace ot the strip 18. 1n the operation of opening the valve, however, the valve handle or lever is rst given a quarter turn, resulting in the contact member 1&1 coming into contact with the strip or plate 18 in passing the same. 'it will thus be seen that in this quarter revolution of the handle, the valve 13 is not only opened suliiciently to permit a quantity of gas to pass to the lamps, but an electrical contact is produced between the members 14b and 18, which results in closing electric lighting circuits through a suitable arrangement of battery, coils and wires which lead to the lamp burners. is the movement of the handle is continued another' quarter tnrn, it is obvious that the production of the lighting sparks at the lamp burners, is discontinued and the plied.

lin view ot the tact that l do not care to online my invention to the exact method ot wiring the parts hereof to produce thc light .ing spark, l have not illustrated. or described the wiring systen'i. lt will be observed, lwwever, that the connection with the contact plate 18 is illustrated in Figs. 1 and 3 ot the drawing, in which ligures one of the conducting wires 19 is shown.

lt will be readily understood that in the operation ol my device, it is desirable that the operating handle or lever stands in a predetermined relation with the contact plate 18 when the valve 13 is closed, so that a Ypredetern'iincd quantity ot gas will be liberated from the passage l during the movement of said valve handle necessary to el'ect the spark producing contact ot the members 14th and 18. ln view of the fact that this relative arrangement ot parts might be changed by the wearing ot the valve termination 18L ol the needle point valve 18, l have provided means for changing the position. or resetting the handlel le on the stem 18, this means consisting` in the loosening oi the screw 1:3 and tightening the same when the handle has been moved to its proper position.

From the construction and operation described, it will be observed that comparatively simple and inexpensive although positive means are provided for supplying gas burners with gas and igniting the same by one operation and although t-he construction described is I iarticularly adapted tor use in the lighting oit automobile lamps, it is obvious that the same .may be applied to lamps used for other pui-posea llhile i. have herein shown and described one particular embodiment of my invention, l'. wish it to be understood that l do not conline. myself to all the precise details of construction sct forth herein, as modification and variation .may be made without departing from the spirit of the invention or exceeding the scope ot the appenc ed claims.

lllhat l claim, is l.. fr fuel and ignition control comprising sation-ary casing having communicating receiving and delivery chambers formed therein, an initial regulating valve in the receiving chamber to initially determine the supply of fuel thereto, a controlling valve in said delivery chamber regulable to vary the flow oi" to said chamber, and means elfiective by the operation of said last named valve to close an igniting circuit.
